Abstract (en)
Minimum friction, tapered or cylindrical roller bearings consisting of rollers (3) having two or more different diameters (d / d1 / d2 / d3) leaning on and rolling over the raceway inner (2) and outer (1) rings, and having equality relationships between them; that is to say, the relationship between the outer raceway diameter (D1) and the supporting roller diameter (d1) keeps the same proportion to that of the inner raceway diameter (D) with the leaning and rolling roller diameter (d), so that the peripheric speed developed by the roller (3) is the same both for the outer raceway ring (1) and the inner raceway ring (2). Being the rollers (3) and rings (1 and 2) peripheric speed the same, there are no slippages, achieving minimum friction and avoiding heating, wear, clearances and noises, improving the accuracy, service life and obtaining a superior performance from the tapered or cylindrical roller bearings. <IMAGE>
